“…The results of a study performed by De Viteri and Fuentes [23] showed that the protective oxide layer can be removed from the surface of metals. This phenomenon occurs by applying contact loads which allows metals to have interaction with the surrounding environment (or the adjacent material).…”

The need for metallic biomaterials will always remain high with their growing demand in joint replacement in the aging population. This creates need for the market and researchers to focus on the development and advancement of the biometals. Desirable characteristics such as excellent biocompatibility, high strength, comparable elastic modulus with bones, good corrosion resistance, and high wear resistance are the significant issues to address for medical implants, particularly load-bearing orthopedic implants. The widespread use of titanium alloys in biomedical implants create a big demand to identify and assess the behavior and performance of these alloys when used in the human body. Being the most commonly used metal alloy in the fabrication of medical implants, mainly because of its good biocompatibility and corrosion resistance together with its high strength to weight ratio, the tribological behavior of these alloys have always been an important subject for study. Titanium alloys with improved wear resistance will of course enhance the longevity of implants in the body. In this paper, tribological performance of titanium alloys (medical grades) is reviewed. Various methods of surface modifications employed for titanium alloys are also discussed in the context of wear behavior.

“…Due to the fast population aging, a concern related to the development of suitable materials for bone replacement is continuously arising. 1,2 Specifically, the aim of current investigations is to develop orthopaedic implants that can stand for longer periods of time or even the entire lifetime without failure or need for a revision surgery. 3 These orthopaedic implants must therefore show bio-and mechanical-compatibility with bone.…”

“…8 So far, the mostly used Ti-based alloys are Ti-6Al-4V (composed of α and β phases) and (composed of β phase). 1,5,[9][10][11] Both materials have found applications in many medical devices as biomaterials for orthopaedic implants because of their outstanding mechanical properties. 3 Nevertheless, these alloys face some undesired and unsolved problems.…”

Nanostructured Ti‐Zr‐Pd‐Si‐(Nb) bulk metallic composites: Novel biocompatible materials with superior mechanical strength and elastic recovery

The microstructure, mechanical behaviour, and biocompatibility (cell culture, morphology, and cell adhesion) of nanostructured Ti45Zr15Pd35‐xSi5Nbx with x = 0, 5 (at. %) alloys, synthesized by arc melting and subsequent Cu mould suction casting, in the form of rods with 3 mm in diameter, are investigated. Both Ti‐Zr‐Pd‐Si‐(Nb) materials show a multi‐phase (composite‐like) microstructure. The main phase is cubic β‐Ti phase (Im3m) but hexagonal α‐Ti (P63/mmc), cubic TiPd (Pm3m), cubic PdZr (Fm3m), and hexagonal (Ti, Zr)5Si3 (P63/mmc) phases are also present. Nanoindentation experiments show that the Ti45Zr15Pd30Si5Nb5 sample exhibits lower Young's modulus than Ti45Zr15Pd35Si5. Conversely, Ti45Zr15Pd35Si5 is mechanically harder. Actually, both alloys exhibit larger values of hardness when compared with commercial Ti‐40Nb, (HTi‐Zr‐Pd‐Si ≈ 14 GPa, HTi‐Zr‐Pd‐Si‐Nb ≈ 10 GPa and HTi‐40Nb ≈ 2.7 GPa). Concerning the biological behaviour, preliminary results of cell viability performed on several Ti‐Zr‐Pd‐Si‐(Nb) discs indicate that the number of live cells is superior to 94% in both cases. The studied Ti‐Zr‐Pd‐Si‐(Nb) bulk metallic system is thus interesting for biomedical applications because of the outstanding mechanical properties (relatively low Young's modulus combined with large hardness), together with the excellent biocompatibility. © 2014 Wiley Periodicals, Inc.
